Product Description

When a spark plugs fires, it engenders radio frequency and electromagnetic interference, which can wreak havoc with electronic ignitions, fuel injection, and engine management systems. This can cause cross talk between wiring harnesses, resulting in poor running, misfiring and decreased performance. If you need a replacement for the spark plug wire set on your 1993-1997 Toyota Corolla, NGT aftermarket sets boast outstanding durability and consistent performance. They utilize a construction method known as "variable pitch" wire winding to create resistance to radio frequency interference. The variable pitch winding (loose/tight/loose) provides suppression throughout a very wide range by "scrambling" and breaking up the electrical waves radiated by the firing of the spark plugs
